Bibliometric review of 506 rTSA papers in JSES (2004-2025) shows rising volume and evidence quality, a shift toward lateralized designs and osteoarthritis indications, and falling revision-focused work.
Three preoperative subacromial ACP injections were associated with modestly lower histologic degeneration scores in supraspinatus tendons at repair (54 patients), but the differences were small and clinical relevance is unclear.
About 8% of 149,024 Bankart repair patients visited the ED within 90 days, mostly early; smoking, Medicaid, depression and open (versus arthroscopic) repair were among the strongest independent predictors.
On ankle CT review, the posterior-harvested congruent-arc distal tibial allograft consistently produced positive glenoid concavity and slope, whereas the traditional lateral graft produced negative values, suggesting better restoration of the glenoid contour.
In 22 children with persistent nerve palsy after supracondylar fracture, ultrasound detected abnormality in 95% but matched operative findings variably, so it should supplement, not replace, clinical judgment in deciding on exploration.
After superior capsule reconstruction with fascia lata autograft in 30 patients, Doppler ultrasound showed all grafts developed angiogenesis peaking around 6 months, unrelated to pain or function, suggesting normal graft healing rather than inflammation.
Predictive Modeling of Clinically Apparent Shoulder Periprosthetic Joint Infection (PJI).
Using prospective data from 861 revision shoulder arthroplasties, authors built a seven-factor nomogram estimating probability of clinically apparent shoulder PJI (concordance 0.90); external validation is still needed.
In a large Ontario cohort of radial head fractures, arthroplasty had a lower reoperation rate than ORIF (10-year cumulative incidence 10.4% vs 15.8%), and overnight ORIF in patients under 40 carried higher reoperation odds.
In this retrospective study of 135 patients, starting rehabilitation early after arthroscopic rotator cuff repair was associated with less 3-month stiffness and better scores, but the observational design cannot prove causality.
In 438 operatively treated proximal humerus fractures, higher neighborhood Social Vulnerability Index was linked to more reoperations (11.6% overall; 6.4% to 16.1% across quartiles), while Area Deprivation Index was not; findings need external validation.
In 60 Gartland III supracondylar fractures, closed reduction and pinning beat open approaches for operative time, union, and cosmesis; among open approaches, anterior did best and posterior worst.
Across 3,473 shoulder studies from 2015-2025, PROMIS use rose to only 5.5% and was usually paired with legacy scores, showing limited adoption as a primary outcome measure.
In 213 junior tennis players, dominant-arm humeral retrotorsion exceeded the nondominant side, with asymmetry appearing from age 10 and stabilizing near 10 degrees from age 13, likely reflecting altered growth-related derotation.
In 41 patients, arthroscopic bone-block stabilization with distal clavicle autograft gave significantly improved Oxford scores, 93% graft union, no donor-site morbidity, and 2.4% recurrent instability at mean 37 months.
At 10+ years after arthroscopic Bankart repair with remplissage in active-duty servicemembers, outcomes stayed improved, with 9% complications, 86% returning to duty, and 13.6% medically discharged.
The 2025 International Consensus Meeting updated the shoulder PJI definition: purulence or sinus tract define definite PJI, and weighted minor criteria score likelihood, with unanimous delegate agreement.
The learning curve associated with robotic-assisted shoulder arthroplasty: A feasibility study.
In a single surgeon's first 19 robotic-assisted shoulder arthroplasties, NASA-TLX workload scores indicated a learning curve breakpoint at three to five cases, proving more reliable than operative time.
A multilayer perceptron model predicted MRI-defined 6-month retear after arthroscopic rotator cuff repair well on random splits, but performance dropped sharply on temporal validation, so external validation is needed before clinical use.
Comparing two press-fit anatomic radial head prostheses, the longer aligned-stem ALIGN design had far fewer radiolucencies (12% vs 50%) with similar function at 2 years; osteolysis was linked to residual pain.
This review covers diagnosis and conservative and surgical management of varus-posteromedial rotatory instability of the elbow, stressing early recognition to avoid arthritis, stiffness, and other long-term complications.
Consensus recommendations from the British Elbow & Shoulder Society for rehabilitation after arthroscopic anterior shoulder stabilization, including early movement limited to elevation up to 90° with neutral rotation, and noting evidence gaps.
British Elbow and Shoulder Society patient care pathway: Frozen shoulder.
Updated British Elbow and Shoulder Society GRADE-based guideline offering evidence-based recommendations for managing frozen shoulder in primary and secondary care, and highlighting areas needing further research.
Clinical features in rotator cuff calcific tendinopathy: A scoping review.
Scoping review of 50 studies finds rotator cuff calcific tendinopathy typically presents as acute, severe, nocturnal unilateral pain in women aged 30-60, often with diabetes or thyroid disorders, aiding early suspicion before imaging.
This scoping review of 145 studies found bioactive and bioinductive implants increasingly used in sports medicine, but the evidence is mostly small, level IV, and uncontrolled, so larger comparative long-term studies are needed.
Management of Lateral Epicondylosis.
Updated review of lateral epicondylosis management, noting most patients improve with nonoperative care while the best nonsurgical modality and the role of surgery in refractory cases remain debated.
A scoping review of 21 studies found cross-body and sleeper stretches are the most studied and seem effective for posterior shoulder tightness, with scapular stabilization improving the stretch and horizontal adduction range of motion.
Protective Sport Bracing for Athletes With Mid-Season Shoulder Instability.
This review of functional bracing for in-season shoulder instability in athletes finds mixed, low-quality evidence with possible return-to-play benefit and minimal downside, making bracing a reasonable individual choice, especially in high-risk sports like football.
Narrative review finds robotic-assisted total shoulder arthroplasty is not yet commercial and supported only by preclinical studies, though lessons from hip and knee robotics suggest it is coming.
Review of how supraspinatus tendons respond to overuse damage, noting that age, smoking, diabetes, and excess load drive degeneration, and that ultrasound can track tendon health in real time.
